Rats have started fighting – what should you do? - briefly
Separate the individuals by installing barriers or relocating one to a different enclosure, then check each for injuries and seek veterinary treatment if needed. Reduce aggression triggers by increasing space, ensuring abundant food and water, and monitoring for territorial behavior.
Rats have started fighting – what should you do? - in detail
When you discover that the rodent population in a building has turned hostile, immediate action is required to prevent injury, property damage, and the spread of disease.
First, secure the area. Close doors and block entry points to stop the animals from moving into occupied spaces. Use heavy gloves and a mask if you must enter the zone, because fighting rodents release blood, saliva, and urine that can carry pathogens.
Second, separate the combatants. Place sturdy traps—snap, electric, or live‑capture models—along the pathways the animals use. Position traps near walls, behind appliances, and in dark corners where activity is observed. Check traps at least twice daily; remove any captured individuals promptly to avoid further aggression.
Third, eliminate the underlying cause. Aggression often stems from competition for food, water, or shelter. Conduct a thorough inspection for accessible food sources: uncovered trash bins, spilled grain, pet food left out, or leaking pipes. Seal containers, clean surfaces, and repair leaks.
Fourth, deny future entry. Inspect the exterior for gaps larger than ¼ inch and seal them with steel wool, caulk, or metal flashing. Install door sweeps and repair damaged screens.
Fifth, consider professional intervention. If trap counts exceed a dozen per night, if injuries are observed, or if the infestation spans multiple units, a licensed pest‑control operator can apply bait stations, rodenticides, or integrated pest‑management strategies safely and legally.
Finally, monitor the situation for at least three weeks after removal. Maintain sanitation practices, keep traps set as a precaution, and conduct periodic inspections of entry points. Consistent vigilance prevents re‑establishment of a hostile rodent population.
